From my limited tarsyn experience, I quickly realized gyros are very dirt & shock sensitive. Just imagine the constant abuse they would see on sidewalk America. No way.

They would be sealed and shock mounted, like an aircraft gyro. Yep. It could work.

I suspect that the reference may be to an 'electronic' gyro which controls the wheel motors. Wouldn't do much if the batteries run out if so, though....

"gyros are very dirt & shock sensitive."

It uses solid-state gyros. It isn't using big, high torque gyros for "brute force" to maintain level posture, it's using tiny sensor-only gyros to detect microscopic changes in angle of attack.
